Modular valve prosthesis, delivery system, and method of delivering and deploying a modular valve prosthesis

A delivery system for delivering a modular valve prosthesis, the delivery system comprising:

• an outer sheath surrounding an inner shaft, the outer sheath including a capsule at a distal portion thereof,
• wherein in the capsule is configured to maintain the modular valve prosthesis in a radially compressed delivery configuration for delivery to a treatment site, and wherein the capsule is configured to be retracted to release the modular valve prosthesis at the treatment site,
• wherein the capsule includes a first section and a second section, wherein the first section and the second section are aligned with a corresponding first and second modules of the modular valve prosthesis when in the radially compressed delivery configuration,
• wherein the capsule includes a first band between the first section and the second section wherein the first band is configured to be aligned with a first gap between the first module and the second module in the radially compressed delivery configuration, and wherein the first band is more flexible than each of the first section and the second section.

A method of delivering and deploying a modular valve prosthesis comprising the steps of:

• manipulating a delivery system loaded with modular valve prosthesis in a radially compressed delivery configuration to guide the modular valve prosthesis through a patient's vasculature to a treatment site, wherein the modular valve prosthesis comprises an inflow stent, a valve component, and an outflow stent, wherein the delivery system comprises an outer sheath including a capsule, wherein the capsule includes a first section, a second section, a third section, a first band disposed between the first section and the second section, and a second band disposed between the second section and the third section, wherein the modular valve prosthesis is loaded within the capsule with the inflow stent aligned with the first section, a first gap between the inflow stent and the valve component align with the first band, the valve component aligned with the second section, a second gap between the valve component and the outflow stent aligned with the second band, and the outflow stent aligned with third section, wherein the delivery system further includes a plurality of sutures coupled to a hub and extending through each of the inflow stent, the valve component, and the outflow stent;
• retracting the capsule proximally to release the inflow stent from the capsule such that the inflow stent transitions from the radially compressed delivery configuration to a radially expanded deployed configuration;
• retracting the hub such that the sutures are taut;
• retracting the capsule proximally to release the valve component from the capsule such that the valve component transitions from the radially compressed delivery configuration to the radially expanded deployed configuration and the valve component couples with the inflow stent;
• retracting the hub such that the sutures are taut;
• and
• retracting the outer sheath proximally to release the outflow stent from the capsule such that the outflow stent transitions from the radially compressed delivery configuration to the radially expanded deployed configuration and the outflow stent couples with the valve component.
